Im a second year apprentice I’ve been doing FA for almost 10 months and I’m starting to understand how it works. I listen to your videos while I’m at work doing fire alarm. There are very helpful and easy to understand thank you so much !
Your videos are awesome. I was forced to change industries at 48. And 4 years later, with drive and a learning hungry soul, you've helped me become one of the leaders of our branch.
Thank you so much for this. I am starting a job as an installer in 3 days and your videos have given me so much training. Now when I show up for my first day on the job I will actually have some idea of what the boss is talking about! You are awesome man, and I really hope you do more videos. I'm only on video 12 but I am definitely going to finish the series. I just wanted to let you know how much you have helped me and how much I truly appreciate it.
@@kershaw1450 Not a project manager! I can do without the stress. But I am NICET II in Fire Alarm Systems and I have been a technician ever since. I love troubleshooting and these videos helped to fuel that fire endlessly for me. Still very appreciative of this video series and recommending it to new guys as often as I can!
Summary A "conventional panel" is driven by 24V DC source FACP (Fire Alarm Control Panel) [probably on a battery] rectified by a transformer and diode from 120V AC mains power. The fire alarm system is built of of sensing circuit completion (10mA? to verify there are no wiring faults like a broken wire) and current draw (500mA? to set alarm state when the circuit is shorted). I'm not sure what the actual current draw is, I'm just making it up. There are 3 states to a monitored area: 1. Trouble (wiring is broken) [0.0mA] 2. Safe (no fire) [10.0mA] 3. Alarm (fire) [500.0mA] Smoke detectors and manual alarms are placed in series for each area that is designed to support an alarm state. Smoke or a human activating an alarm will short the circuit, deliver higher current to the FACP, and trigger the alarm. Video Schematic Devices Shown 1. SD (top): Smoke Detector 2. S (middle): Pull Station (manual alarm pulled by a human) 3. Fire Alarm Control Panel (bottom): Summary overview of alarm state Take-aways 1. The smoke detectors and pull stations are "open contact devices" 2. the smoke shorts the detector or a human shorts the pull station, which are normally open circuits 3. The control panel sees the amperage increase on the wire and triggers an alarm state
I really respect your work. As the youngest osha cert. Nicet lvl1 technician in my state, i wouldnt have been able to pass without ur videos. Thank you
Joe! I just want to thank you so very much for your straight-ahead no-nonsense help with understanding fire alarm systems... you are a huge huge help. can’t thank you enough
I just started as an alarm tech. Went to school to be an electrician and was surprised at how lost I was with low voltage. These videos have helped tremendously thank you.
Woah. ... ... Maybe I should use this as my digital fire alarm school. It seems like I could get alot of info out of this. Thank you Joe Klochan, i'll check out the rest of this series.
Great job....thanks. We walked up 12 floors yesterday to find a bad circuit on the standpipe system. Water flowing into the drain and I believe the sprinkler system was charged.
thank you for your videos . iam bengineer in fire alarm could you tell me the profile of resistance at the end of loop? can i put it instead in pull station to complete the circuit?
Thanks a lot I have collected a few fire alarms and panels so I made a system but it did not work so I bought a pull station and it still did not work so then I looked on RUclips found this video and I made a working system.
Very informative videos but you should have titled them "Introduction to fire alarm circuitry". For the duration of these videos you should work on consolidating the information and include scenarios. Other than that I think you've done a good job.
Can I connect two working fire alarm panles on to another in an adjacent building so that all three buildings will alarm? They are Honeywell FS90 panels so can I use the spare zones in one panel for the other two panels?
Hi Joe. I’m leading a team of FA designers and love your videos as they are super helpful for both them and myself. Question: do you have any suggestions for FA design software? We design everything in AutoCAD but we spend hours addressing/labeling devices and circuits etc... just curios. Keep it up!!
Jeremy, I don't do design, though I have an interest in getting into it. I had some phone conversations with AlarmCAD in the past. Their program seems pretty cool, and I think the stuff you say slows you down is completely automated in their program. There are other companies too that sell programs that run alongside Autocad. If you do a Google search for fire alarm cad software they all come up. I think if you do fire alarm cad drawings full time you'd make your money back pretty quickly.
Is there a way to recover/bypass a passcode? Usually we keep it default,however one school's password is different and im told that its impossible to fix a "Corrupted Program" without the password. Any solutions?
Hi Joe,I have a question. I live in Florida and i am trying to find a school that teaches this. so i can be certified to do this work. i keep googling schools that teach this and it keeps giving me different stuff. how else can i look this up that will put me in the right direction. Thank you Scott from Fl.
SCOTT RUGGIERO In case you haven't found any information on this, you can start a fire alarm apprenticeship. In most cases an apprenticeship is on the job training which you'll be paid for as well as some supplemental classes in the evening which you likely won't be paid for attending. That's generally the best route to go. After you've reached the required OTJ and class hours for your area, you'll be able to take your NICET test. See if there's an International Brotherhood of Electrical Workers (the electrical union) local or an Independent Electrical Contractors office in your area that can help point you in the right direction.
I don't get when you say there is more current when a contact closes then in its normal state because you wont be drawing current for the EOL and there will be no load on the circuit now
The current drawn by the EOL is minimal because the value of the EOL is several thousand ohms. When the contacts close, the current flow increases because the resistance decreases from several thousand ohms to just a few ohms, which is the inherent resistance of the wire.
Match Box in California residential housing, pull stations will be visually tested semi-annual, and physically tested every annual inspection. And when the 5-year testing comes around you drain the sprinkler system, and do an annual along with it.
If you want more info on NICET check out firealarmsonline com and make sure to join our facebook group titled Fire Alarms Online for NICET. I was only 28 years old when I achieved my NICET level IV. It takes a minimum of 10 years to get this level so I was actually as young as possible to get it. Good job and it would be an honor to have you join our group.
It will better if there are lyrics with the video because your accent for me is difficult to understand and may i ask from you if you could write these words and sentences that you said in this video in a comment

Well how did the job work out?
@@Hoax711 dang 8 years ago is this guy a project manager now?
True, the must be far away now

Finally i found the one guy that is explaining this in a way i can understand, thank you! Thank you much!!!
i am integrating my skill with fire alar system and your video is the source my force
I really respect your work. As the youngest osha cert. Nicet lvl1 technician in my state, i wouldnt have been able to pass without ur videos.
Thank you
Joe! I just want to thank you so very much for your straight-ahead no-nonsense help with understanding fire alarm systems... you are a huge huge help. can’t thank you enough
Your channel is GOLD
So clear than whomever and whatever I asked and read. Thank you so much. You're going to heaven!
I just started as an alarm tech. Went to school to be an electrician and was surprised at how lost I was with low voltage. These videos have helped tremendously thank you.
lot of respect to you Mr.Joe.. thanks for sharing tons of knowledge
Joe, this is fantastic! Thanks for taking the time to create these videos
Thx I'm only 14 and my dad is working as a fire and security person and I want to have same job as him
frostbite 958 hell yeah!
I’m 15 my dad does the same thing
It’s a good career guys, follow your dads foot steps and learn everything he knows!
I just came upon this video and your comment. Are you a Fire security technician now?
Did you do it?
Awesome thanks for these videos man. I’m An electrician, and just getting into a multi school alarm system
Thank you for these videos, I wish my employer would provide this type of educational videos. I'm glad I came across your videos.
Woah. ... ... Maybe I should use this as my digital fire alarm school. It seems like I could get alot of info out of this. Thank you Joe Klochan, i'll check out the rest of this series.
Thanks for posting this video. It's really helpful.
I am an enthusiast with some decent knowledge, but I am going to watch this series and learn more :P
So well explained ,really helps understand all the principles of fire systems
cheers to you joe, awesome tutorials, this has really helped me understanding every bit of fas. Thanks alot. Stay blessed...
Thank you very much for this, Joe
your effort is much appreciated indeed.
will definitely watch all of the videos in this series.
good stuff man. Always wondered what that resistor is for
Thanks a lot for all your videos.They are the best.
Great video. Now I finally know what an EOLR is and does.
Great job, I like the simplicity combined with the factual...
Thanks for sharing your knowledge and so clearly. Will watch all your videos. Michael
You’re the best.
Great job....thanks. We walked up 12 floors yesterday to find a bad circuit on the standpipe system. Water flowing into the drain and I believe the sprinkler system was charged.
U the only one that make f a easy thanks lot
Great information made clear for everybody to understand
can you explain more about zones? what are the basis on how many zones are required in one building?
your videos are helping me a lot thanks!!.
Very good intro
thank you for your videos . iam bengineer in fire alarm could you tell me the profile of resistance at the end of loop? can i put it instead in pull station to complete the circuit?
The best info !!!
no words to say you thanks . great Joe
Thanks a lot I have collected a few fire alarms and panels so I made a system but it did not work so I bought a pull station and it still did not work so then I looked on RUclips found this video and I made a working system.
Thanks I needed a refresher
How to get the simulation or the drawing board you use for the interface?
sir, how many zone monitoring modules can be installed in a loop? thanks in advance
Great videos. Learning a lot
really well explained! Keep the good work going!
i have one dought if any smoke detector cammunication error this adressble type if we on"t have spare they any solution for errase camunication error
Do you have a video just about a FACP?
what programs are you using?
Great videos.. can you do videos on plcs?
and what happens if the live or positive wire is cut off does it signal in the panel showing a fault of the alarm just stops working
Very informative videos but you should have titled them "Introduction to fire alarm circuitry". For the duration of these videos you should work on consolidating the information and include scenarios. Other than that I think you've done a good job.
wow this video is really helpful
In this conventional system all zones have separate loop detectors loop with mcp & sounders loop come separate to Facp , i am right
Thank You Sir its really useful.
Can I connect two working fire alarm panles on to another in an adjacent building so that all three buildings will alarm? They are Honeywell FS90 panels so can I use the spare zones in one panel for the other two panels?
BenOfficial505 It can be done....
Great job!
Why the multimeter mark 17 volts but when I put the resister it says 7 volts ?

Really appreciate the feedback
Is there a way to recover/bypass a passcode? Usually we keep it default,however one school's password is different and im told that its impossible to fix a "Corrupted Program" without the password. Any solutions?
That totally depends on the type of panel. What make/model are you dealing with?

If positive wire gets open of Mcp then same condition will happen i mean the panel shows an open circuit trouble
Can you put this series for download
very well done
really useful thank you
Thanks Bro may Allah bless you , you explained the things with such a great detail and simplicity.
What value is the end of line resistor?
That always depends on the panel.
great video
waht program is this
make one vedio on est3 Edwards

how often is a pull station tested? pop quiz question, but it contradicts itself in two quizzes i need clarity please.
Match Box in California residential housing, pull stations will be visually tested semi-annual, and physically tested every annual inspection. And when the 5-year testing comes around you drain the sprinkler system, and do an annual along with it.

Plz demo a addresable fdas
what if i decide to connect the resistor inside the control panel?
Then the circuit isn't supervised. If wires were cut in the field, you'd never know
Great video! I Didn’t know that smokes and pulls could be on the same input! With my ocd I’ve always put smokes, pulls, and WF in separate zones
no problem if you have enough zones
I thought the eol of a slc circuit didn’t need a resistor
It doesn't. This is a zone system.
Thanks!
You can’t put smokes and pulls on the same zone on a conventional panel as far as I know.
Thank you .... bro
where are u work
Chicago
It will better if there are lyrics with the video because your accent for me is difficult to understand and may i ask from you if you could write these words and sentences that you said in this video in a comment
Mohammd Magdy its 9 months later but mate there is a caption section in youtube for auto generation of subtitles.
well done I spent 2 years in trade school for electritian and the teacher didn't know shit
would have been a lil' bit more helpful if you would've explained about the SD ....
Parashar Sangle smoke detector
A good fire alarm installer should never put a pull station and a smoke detector on the same zone.
Why?
This isn't 20 years ago lol
